Problem with Select and using wildcard characters

[snpcrd]

Hi,Having a problem selecting records from an Access 2003 database. With the below SQL from what I understand it should select all records in the database based on using the wildcard character '%'.

SELECT * FROM Unsnooped WHERE RegionCode LIKE '%' AND ClinicGroup LIKE '%' AND Snooped LIKE '%' ORDER BY Sitecode ASC 

Example DB records can be found at . The rightmost field is the one called 'Snooped'. There are 1033 records in the DB but it will only display 496. All the fields that I'm trying to pull out are populated by values so I'm a bit of a loss.Cheers

The WHERE clause is superfluous increases unnecessary overhead if you're trying to select all records. Do this instead:

SELECT * From Unsnooped ORDER BY Sitecode ASC

I don't use Access a lot, but I'm pretty sure your problem traces back to MS Access' handling of nulls. A null is not the same as an empty string, so if one of your RegionCode, ClinicGroup, or Snooped fields contains null data, it won't be returned in your dataset.
